Log Message:
Add 'syscallemu' module, required by usermode kernel.
This module registers a syscall that takes a user_start and user_end address.
When a process calls SYS_syscallemu, the start and end address are recorded
and the syscall installs a filter on p->p_md.md_syscall. The filter then
uses the specified start and end addresses to determine where the syscall
should be routed (either host by calling the original md_syscall function,
or process by posting SIGILL).
